In English, a new word can be formed by adding a prefix or a suffix to a base word. An example is:
  1. act + ive = active
  2. in + active = inactive
  3. inactive + ty = inactivity
  4. inactivity + es = inactivities.

    Step 4 is inflectional. This word forming process, in linguistics, is called morphological process, which took place at certain order in a word' history. For example, the following order is not legal, as prefix in, in the sense of not, opposite, cannot be added to a noun.
  1. act + ive = active
  2. active + ty = activity
  3. in + activity = inactivity ?
  4. inactivity + es = inactivities.

    This parser captures and displays the morphological process of any English word, even a word coined by you playfully, provided it is not a compound word.
